In a world of floating islands, each landmass is imbued with an ancient elemental magic that forms its landscape, flora, fauna, and resources. The peaceful balance of the islands has been upset by Lord Xanthos as he seeks to unseal a sealed powerful island in order to amass total control over all elementals.
The air thrummed with an alien energy, a tapestry woven from starlight and whispers. On the windswept, cloudswept floating island of Caelum, young elementalist Eira struggles to control the growing rush of air magic within her veins that threatens to further deteriorate the delicate floatstone underneath her home.

This is just the beginning. The secrets of Skykeep await, and Eira's curiosity is piqued as she disregarding logic and fear embarks on a desperate quest to solve the mystery of the island...
